Processing device and recording device

Abstract

A recording device as a processing device includes: a recording unit accommodated in a housing and configured to perform recording on a medium; and a medium accommodating unit that accommodates the medium discharged from the housing. The medium accommodating unit includes: a sheet-shaped accommodating member; a rotating shaft provided inside the housing and to which one end of the accommodating member is connected; and an operating portion provided separably from the housing and to which the other end of the accommodating member is connected. The accommodating member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing. The accommodating member is fed from the rotating shaft so that the medium is accommodated when the operating portion is separated from the housing.

What is claimed is: 
     
       1. A processing device comprising:
 a processing unit accommodated in a housing and configured to process a medium; and 
 a medium receiving unit that receives the medium discharged from the housing, the medium receiving unit including: 
 a sheet-shaped receiving member; 
 a rotating shaft provided inside the housing and to which one end of the receiving member is coupled; 
 an operating portion provided separably from the housing and to which the other end of the receiving member is coupled; 
 a pair of support portions that protrude from the housing in a retractable manner and supports both ends of the operating portion; 
 a rack provided on at least one of the pair of support portions; 
 a rotating shaft gear provided on the rotating shaft and configured to rotate in conjunction with movement of the rack; and 
 a speed increasing mechanism provided between the rack and the rotating shaft gear and configured to increase a rotation speed of the rotating shaft gear so that a feeding amount of the receiving member is greater than a movement amount of the pair of support portions, wherein 
 the receiving member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing, and 
 the receiving member is fed from the rotating shaft so as to receive the medium when the operating portion is separated from the housing. 
 
     
     
       2. The processing device according to  claim 1 , wherein
 the rack is provided on both of the pair of support portions. 
 
     
     
       3. The processing device according to  claim 1 , wherein
 the speed increasing mechanism includes a composite gear in which gears having different numbers of teeth are stacked. 
 
     
     
       4. The processing device according to  claim 1 , comprising:
 a contact portion that comes into contact with an outer circumferential surface of the receiving member wound around the rotating shaft to press the receiving member against the rotating shaft. 
 
     
     
       5. The processing device according to  claim 4 , wherein
 the contact portion is provided at both ends in an axial direction of the rotating shaft. 
 
     
     
       6. The processing device according to  claim 4 , wherein
 the contact portion has a contact roller that is driven by rotation of the receiving member. 
 
     
     
       7. The processing device according to  claim 6 , wherein
 the contact roller is provided between a straight line that is a horizontal line intersecting an axis of the rotating shaft and extends from the rotating shaft toward the operating portion, and a straight line that is a vertical line intersecting the axis of the rotating shaft and extends upward from the rotating shaft. 
 
     
     
       8. The processing device according to  claim 4 , comprising:
 an auxiliary roller that comes into contact with an outer circumferential surface of the receiving member wound around the rotating shaft below a horizontal line intersecting the axis of the rotating shaft. 
 
     
     
       9. The processing device according to  claim 1 , wherein
 an opening through which the receiving member is fed is formed in the housing, and the opening is blocked in a state where the operating portion is mounted on the housing. 
 
     
     
       10. The processing device according to  claim 9 , wherein
 the operating portion has a front plate that forms a part of the housing in a state where the operating portion is mounted on the housing. 
 
     
     
       11. A recording device comprising:
 a recording unit that performs recording on a medium as the processing device according to  claim 1 .
